Ue-to-network relay support for n3iwf access

Abstract

Aspects of the disclosure relate to relaying data between a PC5 remote UE and a network entity (e.g., 5G core network entity) via an inter-working function (e.g., N3IWF) over sidelink UE-to-NW relay access. In an example operation, a relay UE establishes a connection with the network entity and determines whether relay access to the network entity via an inter-working function device is supported at the relay UE. The relay UE then indicates, to the remote UE, support of the relay access to the network entity via the inter-working function device. The relay UE receives, from the remote UE, a request to relay data between the remote UE and the network entity via the inter-working function device, and thereafter, relays the data between the remote UE and the network entity via the inter-working function device based on the request. Other aspects and features are also claimed and described.

What is claimed is: 
     
         1 . A method of wireless communication at a relay user equipment (UE), comprising:
 establishing a connection with a network entity;   determining whether sidelink relay access to the network entity via an inter-working function device is supported at the relay UE;   indicating, to a remote UE, support of the sidelink relay access to the network entity via the inter-working function device;   receiving, from the remote UE, a request to relay data between the remote UE and the network entity via the inter-working function device; and   relaying the data between the remote UE and the network entity via the inter-working function device based on the request.
